GRAIN-WEIGHING MACHINE SPECIFICATION forming part of Letters Patent No. 371,148, dated October 4, 1887. Application filed Apr-i118,- 182-7. Serial No. 235,207. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN B. OYER, a citizen of the United States, and a resident of Gridley, in the county of McLean and State of lilinois, have invented certain new and useful linprovemenisin Grain-\Veighing Machines; and I do hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved grain-weighing machine. Fig. 2 is a iront view of the same. Fig. 3 is a bottom View; and Fig.4 is atransverse sectional view on line a; m, Fig. 3.

Similar numerals of referenceindicate corresponding parts in all the figures.

My invention has relation to that class of grain-weighing machines in which the grain is filled into receptacles, which are tilted when filled with a certain quantity of grain, emptyingthe filled receptacle,and bringing an empty receptacle before the discharge-spout; and it consistsin the improved construction and comof such a weighing-machine,

bination of parts more fully described and as hereinafter claimed.

In the accompanying drawings, the numeral -1 indicates the spout from which the grain is discharged, and which in this case is shown extending from the upper end of an elevator, 2, of the usual construction.

Suitable obtuse Vshaped brackets, 3 and 4, are supported under the spout-one, 3, being secured to the e1evator-casing,while the other, 4, is supported by means of braces 5 forward of the same, registering, however, with it, and the ends of the brackets are connected by means of suitable strips or bars, 6.

A board or plate, 7, is secured at its middle to a shaft, 9, having its trunnions 8 journaled in suitable bearings, 10, in the V- shaped brackets, and semicircular side pieces, 11, are secured to the edges of this bottom-board, having a partition, 12, secured between the side pieces upon the middle of the bottom, standing at right angles to the same.

A scale-beam, 13, is secured at its ends in brackets 14 to the under side of the bottom of the 1'eceptacles,'and a poise, 15, slides upon this beam, and may have its throw upon the same adjusted by means of blocks 16, sliding adjustably upon the beam, and having set- I screws 17 for securing them, suitable graduations being made upon the scale-beam to indicate at which weight the receptacle opposite to the sliding poise bearing against the adjustable block will be depressed, causing the poise to slide to the opposite end of the beam, counterbalancing the other receptacle.

Longitndinally-slotted arms 18 are secured to project downward from the apices of the obtusely Vshaped brackets, and V-shaped abutting-brackets 19 have nutted bolts 20 sliding adj ustably in the slots and inserted through their apices, securing the abutting brackets. The ends of these brackets are bent to form suitable abutments for the bottom of the tilting receptacles, one end of the bottom striking one pair of arms of the V-shaped brackets at each time the receptacles are tilted, and by adjusting the said abut-ting brackets higher or lower in the slotted arms the receptacles may be allowed to tilt less or more, as desired. The outer trunnion of the tilting receptacle is provided with a disk, 21, and two pawls, 22, are pivoted with their ends to diametrically-opposite pins 23 upon the disk, having springs 24 bearing from above against them, and having their ends engaging two ratchetrims, 25, upon a disk or wheel, 26, journaled within a suitable glass-covered casing, 28. The ratchet-rims of the disk are separated by a smooth flange, 27, and the pawls will as the receptacle is rocked revolve the disk the space of one tooth each time, so that by suitable inscriptions and indices the number of times the receptacles is tilted to either side may be registered, the ratchet-disk having a long tooth, 29, which engages with another ratchet-disk, 30, which registers the tens, and which disk 30 is provided with a long tooth, 31, which engages the teeth of a ratchet-disk, 32, which registers the hundreds, so that the number of times the receptaclehas been tilted is registered, and consequently the number of the quantities of grain contained in each compartment of the receptacle.

It will be seen thatby adjusting the blocks ICC upon the scale-beam the throw of the poise may be adjusted, and when one compartment of the receptacle is filled with suffieient grain to counterbalance the poise the receptacle will be tilted, emptying the grain out of the tilled receptacle and causing the poise to slide to the overbalaneed side, causing it to keep the empty compartment under the spout to be filled, while the full compartment is emptied and may again be tilted up under the spout when the compartment now being filled is filled.

Having thus described my invention, I claim and desire to secure by Letters Patent ot' the United States- 1. In a grainweighing machine, the combination of a grain-spout, a receptacle consist ing' of a bottom pivoted upon a transverse shaft below the spout, and two semicircular side pieces and a partition between the same at right angles to the bottom, and a scale beam upon the under side of the bottom, and provided with a sliding poise and with adj ustable stops for the same, as and for the purpose shown and set forth.

2. In agrain-weighing machine, the combination of a grain-spout, two frame-pieces secured below the spout, a bottom pivoted with the trunnions of a transverse shaft in the middles of the framepieees rocking transversely to the spout, and having semicircular side pieces and a transverse partition at right angles to the bottom, a scale beam secured upon the bottom and havingasliding poise and stops for the same, longitudinalIy-slotted bars projecting downward from the middles of the framepieces, and V-shaped abutmentbraekets secured adj ustably to the slotted bars by nutted bolts at their apices, and having bent ends at their arms forming abutments for the bottom when tilted to either side, as and for the purpose shown and set forth.

3. In a grain-weighing machine, the combination of a grain-spout, two fran'ie-pieces secured below the spout, a receptacle consisting of a bottom pivoted with the ends of a transverse shaft in the middles of the side pieces, and having two SOl'lllCllCLllElI' side pieces and a partition secured to the middle of the bottom at right angles to the same, a sealebeam secured longitudinally to the bottom and having a sliding poise and adjustable stops for the same, lougitudinally-slotted bars at the middles oi' the frame-pieces, V-shaped abutting brackets secured with nutted bolts at their apices in the slots, and having the ends of their arms bent to form stops for the tilting bottonu a registering device composed of ratchetdisks, and a disk upon one end of the rocking-shaft, having two spring-pawls pivoted to it engaging one of the disks of the registering device, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto alfixed my signature in presence ot'two witnesses.

JOHN B. OYER.
